Stone QUICK-DRYING SCOURENG COMPOSITION This invention is directed to a stable, non gritty scouring composition which leaves the surface to which it is applied dry, shiny and free from a gritty residual film. The instant composition is designed so as to leave the surface which has bee :leaned dry and shiny, thus eliminating the need for subsequent drying and polishing of said surface. In order to remove firmly adherent dirt from a surface of a solid material there have conventionally been employed in households, business enterprises and similar industries scouring agents which are composed predominantly of a water-insoluble component which provides said composition with a mechanical cleaning action. In addition, in compositions of this type, a water-soluble component has conventionally been used in a smaller quantity, said water-soluble component being employed to assist in the cleaning action of the water-insoluble abrasive component. In the past the water-insoluble salts have included ground quartz, marble, limestone, dolomite, pumice stone, or ground rock. In addition to the abrasive agent it has been customary to include in compositions of this type a compound which is useful in the bleaching of a solid surface, such as a compound which yields chlorine when contacted with water. Furthermore, it has been customary to include in compositions of this type anionic and nonionic detergents which impart surface active properties to the composition. The previously used anionic detergents have included sodium dodecylbenzenesulfonate, potassium dodecylbenzenesulfonate, sodium laurylbenzenesulfonate, sodium cetylbenzenesulfonate; the alkali metal salts of the higher alkylsulfonic acids and the alkali metal dialkyl sulfosuccinates, e.g., sodium dioctylsulfosuccinate, and sodium dihexylsulfosuccinate, sodium sulfoethylphthalate, sodium oleyl-p-anisidinesulfonate; sodium tetradecanesulfonate; sodium diisopropylnaphthalenesulfonate; sodium octylphenoxyethoxyethylsulfonate, etc. and the alkali metal alkyl sulfates, e.g. sodium lauryl sulfate. In addition the specific nonionic surface active agents have included alkaryl polyglycol detergents such as alkylphenolethylene oxide condensates (2-200 moles ethylene oxide), e.g., p-isooctyl phenol-polyethylene oxide ethylene oxide units), long chain alcohol-ethylene oxide condensation products (2-200 moles ethylene oxide), e.g., dodecyl alcoholpolyethylene oxides having 4 to 16 ethylene oxide units per molecule, polyglycerol monolaurate, glycol dioleate, sorbitan monolaurate, sorbitan sesquioleate, the condensation products of ethylene oxide with sorbitan esters of long chain fatty acids (Tweens), alkylolamides, amine oxides, phosphine oxides, sulfoxides, etc.

While compositions of this type have been effective, there have been certain problems associated with their use, that is to say,that the insoluble compounds used as abrasives result in an unpleasant gritty residue which is left on the surface on which the composition has been employed. This necessitates spending considerable additional effort to remove this undesirable gritty film.

In an effort to eliminate this problem, it has been suggested to substitute a soluble salt for all or part of the insoluble compound. By substituting a soluble salt for an insoluble one, one obtains a composition which rinses away and leaves no residue, as all the components of the composition are then soluble and are rinsed away in the normal cleaning process. The salts conventionally used in a composition of this type include hydrated salts such as carbonates, bicarbonates, phosphates, borates, and halogen salts of alkali and alkaline earth metals. While these salts eliminated the gritty residue which was formerly a problem, they resulted in a composition which left the surface which was cleaned with a dull appearance.

A further objection to the currently known conventional scouring compositions is that said compositions tend to dry slowly, thus necessitating an additional step in the cleaning process, i.e., drying the surface of the cleaned article. This is necessitated by the fact that if the water remaining on the surface of the cleaned article is left to evaporate, said remaining water results in water marks being left on the sufiace. In addition, the cleaned article takes on a dull, dingy and dirty appearance rather than the bright and shiny appearance one would hope to obtain.

Therefore, it is an object of the instant invention to provide a scouring composition which is rapid drying and leaves a bright and shining appearance on the surface which has been cleaned.

Another object of the instant invention is to provide a composition which leaves the cleaned surface free from a non gritty residual film after a normal cleaning operation.

Another object of the instant invention is to provide a scouring composition comprising a water-soluble salt and a surface-active compound.

Yet another object of the instant invention is to provide a composition comprising a water-soluble salt and a cationic surface-active agent.

Still another object of the instant invention is to provide a composition comprising a water-soluble borate salt and a cationic surface-active agent.

Still another object of the instant invention is to provide a scouring composition comprising a water-soluble salt and an imidaaoline-type cationic surface-active agent.

Yet a further object of this invention is to provide a scouring composition comprising a water-soluble borate salt and an imidazoline-type cationic surface-active agent.

Still a further object of the instant invention is to provide a scouring composition comprising a water-soluble salt, at ca tionic surface-active agent and other conventional scouringcomposition additives such as bleaches, perfumes, builders, germicides and coloring materials.

Yet a further object of the instant invention is to provide a scouring composition comprising sodium borate and 2-alkyll-hydroxyethyl imidaaoline which is made from oleic acid.
